Global IMS Core Network Devices Market Strategic Research Report

Scope of the Report

The global IMS Core Network Devices market size is predicted to grow from US$ 1,638 million in 2025 to US$ 2,389 million in 2032; it is expected to grow at a CAGR of 5.4% from 2026 to 2032.

IMS Core Network Devices are a combination of IP Multimedia Subsystem core network equipment and software network functions deployed in operator networks, public-private networks, MVNO/MVNE networks, and dedicated industry communication networks. They are mainly used to support voice, video, SMS, supplementary services, session control, subscriber data management, media processing, border security, inter-network interworking, and charging over IP bearer networks. These products typically include P-CSCF, I-CSCF, S-CSCF, TAS, SBC, IBCF, MRF, MGCF, media gateways, HSS or UDM-related network functions, and charging functions. Their core value lies in migrating traditional circuit-switched voice to a standardized IP architecture, supporting VoLTE, VoNR, VoWiFi, fixed broadband voice, legacy network interworking, and multi-access convergence. With the deployment of 5G SA, 3G network shutdowns, fixed-mobile convergence, and cloud-based core network construction, IMS core network devices are evolving from physical equipment and virtualized network functions into cloud-native, containerized, and automatically orchestrated software network functions, while gradually expanding from public operator networks to private networks, public safety, energy, transportation, and emergency communications scenarios.

The demand foundation for IMS core network devices comes from the IP transformation of voice services and the convergence of multiple network generations. Although VoLTE, VoNR, and VoWiFi correspond to 4G, 5G, and Wi-Fi access respectively, their core voice control still relies on the IMS architecture. As 3G networks are shut down, legacy circuit-switched cores are replaced, and 5G SA deployment expands, operators need IMS core networks to centrally support mobile voice, fixed voice, roaming interworking, emergency calling, and multimedia communication services. Therefore, the industry value of IMS core network devices is not merely to replace legacy voice equipment, but to help operators maintain voice continuity, service consistency, and network evolution capability in a multi-standard, multi-access, and multi-service environment.

Product forms are shifting from dedicated physical equipment to virtualized and cloud-native software network functions. Traditional IMS systems place greater emphasis on the stability, capacity, and protocol compatibility of individual network functions, while next-generation IMS core network devices focus more on microservice architecture, containerized deployment, automated orchestration, elastic scaling, and cross-cloud operation. This means that future competition will not only depend on whether network functions are complete, but also on whether vendors can reduce deployment complexity, shorten service launch cycles, improve resource utilization, and enable stable interworking across 4G, 5G, Wi-Fi, fixed networks, and legacy voice networks. As core networks continue to move toward cloud-based architectures, IMS core network devices will gradually shift from hardware-driven procurement to competition around software capabilities, system integration capabilities, and continuous operations capabilities.

The overall market outlook is optimistic, but growth will shift from new network construction to migration upgrades and software-based replacement. Future demand will mainly come from 3G network shutdowns, legacy voice core replacement, IMS Core upgrades, cloud-native IMS modernization, large-scale 5G SA deployment, commercial VoNR expansion, enterprise private networks, and edge core network construction. The price of IMS core network devices will not simply decline along with hardware costs, because customers are increasingly shifting their procurement focus from the equipment itself to software licensing, capacity expansion, cloud-native upgrades, system integration, operations services, and long-term network evolution projects. Overall, the industry is expected to maintain steady growth and continue to release demand in operator voice modernization and industry private network communication scenarios.
